    Dedicated Cluster The dedicated cluster to which the host belongs.
    Zone The zone where the host is deployed. We recommend that you deploy hosts in different zones to improve availability.

    Host Instance Type The specifications of the host.

    VSwitch The vSwitch to which the host is connected. If no vSwitches are available, create a vSwitch as prompted below the drop-down list.

    Duration The subscription duration of the host. You can select Auto-renewal. The auto-renewal feature prevents the host from being released due to expiration.
